Compared to traditional wooden sofa legs, plastic sofa legs are more portable and more affordable, a new environmentally friendly concept. A sofa is a type of software furniture, an upholstered multi-seat with armrests on both sides. It originated in Western countries and was later introduced to Asia as one of the focal points of Western decor or modern home design. The frame of the chair is made of wood or steel and lined with cotton and other foam materials, which makes it more comfortable overall. The sofa feet at the bottom of the sofa provide support for the seat and simply prevent damage to the bottom of the sofa from moisture on the floor. Existing sofa feet generally consist of a foot cushion and a base plate, between which the fixing is achieved by welding, which is not only difficult to work with. And when part of the sofa foot is damaged, the whole sofa foot must be removed and replaced, the sofa tilts as a result of the thread holding a portion of the sofa foot to the sofa. The height of the sofa foot varies as a result, which raises the production cost.The plastic sofa feet can balance this tilt and greatly increase the solidity of the sofa feet and also reduce the cost of sofa production, making it a new world for sofa feet.
